I make tator tots in mine. They come out nice and crispy. I have also made fried pork chops and chicken nuggets. Not the frozen kind, but raw with batter and everything. Turned out well and no vat of oil to deal with afterwards.
Get memphis char from the grilling aisle at walmart and put it all over pork ribs and throw them in the air fryer. My wife makes the best ribs in that thing
I own one as a gift but never use it because I don't know what to use it for. I tried to fry peas to make them crunchy and that didn't work. I guess if there's a specific reason you want one it would be worth it.
